Parse line based on highest value
Hello,

Does anyone know how to parse whole line that has highest value in last column (c12), based on the string in column 6 (column VIRUS)

INPUT:
Code:
5	7	4	8	3	VIRUS1	5	5	HUMAN1	8	4	100
6	9	7	2	6	VIRUS1	6	0	HUMAN2	6	2	80
9	6	7	3	7	VIRUS1	9	7	HUMAN3	5	9	70
8	5	3	8	6	VIRUS2	8	6	HUMAN4	8	6	95
4	7	2	7	0	VIRUS2	2	5	HUMAN5	9	1	40
7	4	7	3	0	VIRUS2	4	8	HUMAN6	3	7	75


In the end, I only want one representation of string in column 6 (column VIRUS) that has the highest value in column 12.

OUTPUT:
Code:
5	7	4	8	3	VIRUS1	5	5	HUMAN1	8	4	100
8	5	3	8	6	VIRUS2	8	6	HUMAN4	8	6	95

Thank you so much!
